'Definition of perfect' - 'Pregnant' Kylie Jenner wows fans in lingerie by UK brand on Instagram

Kylie Jenner may be hiding her famous physique following reports of her first pregnancy with boyfriend Travis Scott, but at least the reality television star is covering up in style.

The 20-year-old cosmetics mogul has been keeping a low profile in recent months, opting for close-up selfies and make-up swatches on her Instagram page instead of her typical scantily-clad body shots.

But it appears that the younger half-sister of Kim Kardashian is expanding her sartorial horizons, wowing in a beautiful purple kimono by luxury British lingerie brand Gilda & Pearl for one of her latest Instagram pictures.

The sheer chiffon design features marabou-trimmed sleeves and is handmade on British soil, retailing at £380.

Jenner accessorised the design with glamorous diamond earrings, light pink nails and a flawless matte make-up look in the professional snap taken by LA-based photographer Sasha Samsonova.

Gilda & Pearl, founded by Diane Houston, is a London-based brand that designs and creates every exquisite piece in the UK – known for their pom-pom thongs and elegant nightdresses.

Houston told IBtimes UK: "Having Kylie Jenner wear our Diana kimono really helps us to bring Gilda & Pearl to a wider audience, especially in the US.

"She is very influential – we love that she's already a businesswoman and beauty mogul and, of course, that she flaunts her curves.

"We are a luxury British lingerie and loungewear brand – every piece is made in the UK by highly skilled craftspeople," she added.

Jenner's fans were a big fan of her new demure look, with one person commenting on the photo "Beautiful" as another put "Definition of perfect."

The expectant mother, meanwhile, has been dubbed the new Rob Kardashian by her fellow rumoured pregnant sister Khloe Kardashian after going incognito on social media.

A source close to the famous family told People: "Kylie wants to disappear and be out of the spotlight and focus on her health and happiness."

"Kylie isn't going to publicly address her pregnancy until she gives birth. She's not doing any public appearances and just wanted to take six months off," they added.
